Abstract:
Objective To explore the therapeutic effects of nimodipine and magnesium sulfate on severe pregnancy induced hypertension (PIH) as well as the effect on plasma endotheline (ET) and serum nitric oxide (NO), in order to provide theoretical foundation for clinical treatment. Methods Forty two patients with severe PIH, being divided into 2 groups at random, were treated with nimodipine or magnesium sulfate. The changes of blood pressure, arteriole of eyeground, urine protein, ET, NO and clinical symptoms were observed respectively before and after the treatment, and the pregnancy outcomes were compared. Results (1) After the treatment of nimodipine, the serum NO of patients increased significantly from (51.72?14.64)?mol/L to (67.56?14.77)?mol/L ( P 0.05). (2) The nimodipine group took shorter time (0.5 h) to lower the blood pressure notably than the magnesium sulfate group (2 h).(3) As for the disappearing of subjective symptoms , nimodipine group (1.7? 1.3) h was quicker than magnesium sulfate group (3.4?1.7) h. Conclusions Compared with magnesium sulfate, nimodipine was better in improving and protecting the function of endotheline cells, dilating cerebral blood vessels, depressing blood pressure strongly and persistently, reducing subjective symptoms of patients and had no other side effects except increasing heart rate.
